I got a warranty for my Gateway laptop and had to use it when my hard drive died. After months of bad repair I finally got a working laptop back. However, when i checked the serial for XP I saw that it didn't match the one on my sticker. I'm fairly sure that they were unable to restore the Gateway specific OS that uses the Gateway XP serial on my sticker and instead installed a generic version of windows with a volume key. Is this legit?
